Articles on MATSU Takako's "Ashita Haru ga Kitara"

Hi everyone! Newbie here (hope this thread is not against the rules!) Well, I know it's too sudden, but I have a small favor to ask of you. I am a member of Wikipedia and am currently trying to make MATSU Takako's song "ASHITA, Haru ga Kitara" a good article. Since it as an old song, I'm finding it very hard to find reviews on it. I don't know any Japanese newspaper archived from back when the song was released (in March 1997!). Does anyone have any magazines from back then which includes information on the song? I have searched everywhere, but I guess Japanese magazines/newspapers are not so easy to find as compared to English ones. Please help!
